Generally speaking, once I’ve sketched it, patterned it, cut it I can assemble without a cut/sew assembly sheet. Doesn’t mean to say that from time to time I assemble something too soon in the manufacturing process and then have to rip some seams to add or remove a piece.......all part of the fun of custom gear!Wowza. Can you keep a build like that all in your head, or do you need an assembly checklist? (I needed a list for my much simpler rectangular bags.)
BTW, the outer panel will have 16 pieces giving these bags a total of 31 pieces not including the strap.
